Fan Oven

[peasey]

Fan oven (double) - Not cooker

Can this be plugged directly into a 13A ring main socket?

"or"

Is an independant (dedicated) supply required from the CU to the cooker point?

If yes, what cable 16A or 32A?

Is a DP isolator required? If yes, adjacent CU ok?

What's needed at the CU?

To determine the requirements of any circuit,it is necessary to know what the likely load is going to be,the method of installation and the length of the circuit

The first question would be
What is the rating of the ovens for diversity calculation to be made ?

Plugging it into a 13A socket would probably cost you a lot in fuses at best.

Seperate feed from CU is usually the way to go.

what is the maximum demand of the cooker?

once you have that, apply the old diversity equation.

take off the first 10A
30% of the remainder
add the 10A back on
if you've got a socket outlet incorporated add 5A.

Just make sure that the figure in amps you get after applying diversity, is superceded first by the protective device rating, and then by the maximum current carrying capacity of the cable selected after correction factors have been applied.

All should then be well.

Usually its over 2KW per oven so with both on at approx 4A per KW it would be over 16A.

Double oven will require 32a radial circuit ,

don't guess it, calculate it!

Are you refering to me

 

[jjjinx]

no, but it could apply to your comment if you wanted it to?

It was aimed at peasey, as good advise!
